// just a untested quick-hack
// if it doesn't work, I hope you get the idea
function session_exists( $name=NULL )
{
if( $name === NULL )
$name = ini_get('session.name');
if( ini_get(session.use_cookies) == 1 )
return isset($_COOKIE[$name]);
else
return isset($_GET[$name]);
}

There is no way to detect if a session exists, without creating a
session. This can trigger warnings like this in cookie detectors:
This page wishes to set the cookie
PHPSESSID="bd977b12c9da97f1ba0b07e4fe25a176"
A page needs to generate differently based on whether a user is "logged
in" (a session exists) or just a "visitor".
You shouldn't have to create a session to know if it exists. I suppose
you could manually check cookies & the URL etc but shouldn't there be a
function for this?
